The kldxref utility is used to
generate hint files which list modules, their version numbers, and
the files that contain them. These hints are used by the kernel
loader to determine where to find a particular KLD module.

A separate hint file is
generated for each directory listed on the command line that
contains modules. If no hint records are generated for a particular
directory, no hint file is created, and the preexisting hint file
(if there was one in that directory) is removed.

The following options
are available:

−R

Recurse into
subdirectories.

−d

Do not generate a hint
file, but print module metadata on standard output.

−fhintsfile

Specify a different name for the hints
files than linker.hints.

−v

Operate in verbose
mode.

EXAMPLES

To build hint files for both standard
and add-on modules:

kldxref /boot/kernel
/boot/modules

To build hint files for
all installed kernels:

kldxref -R /boot
